BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE CP-QAP-12.1 5 ypp, ! ; 2 of 17 2.2 SCOPE The scope of this procedure applies. to all ASME Section III piping and components being inspected for release.

2.3 RESPONSIBILITY The QC Group Supervisor shall be responsible for the overall implementation of this procedure.

All inspection personnel perfonning inspections required by this procedure shall be trained, qualified and certified in accordance wi th Reference 1-A.

The Quality Engineering (QE) Completions / Start-up Group Supervisor shall be responsible for supplying Quality Control with all the documentation required to perform piping systen status walkdowns and component support design verifications.

3.0 PROCEDURE 3.1 PREOPERATIONAL/ TESTING WALKDOWN The walkdown status of' the piping system / subsystem snall be perfonned using the "QC Preoperational/ Flushing Checklist" -

! ( Attachment 1), and BRP drawings.

l The following infonnation shall be recorded on the System Verification Fonn (Attachment 7) during preoperational/

testing walkdown:

. .a. Manufacturers' identification / serial nu:nber of all ASME stamped items (i.e. piping subassemblies, valves, pumps and vessels), within the boundries of the BRP.

b. Material identification (i.e., Heat numbers, heat code, material specification) for material suoplied by B&R, if available.

General hanger locations and hanger number for permanent hangers and attachments to piping shall be recorded on the B RP .

j 3.2 PRE-PRESSURE TEST WALXDOWN l

The pre-pressure test walkdown status of the piping system /  ;

subsystem shall be perfonned using the "QC Pre-pressure i Test Checkli.st" (Attachment 2), current BRP drawing, previous BRP drawings and any CMC's that have not been incorporated into the latest drawings. .

Valves, pumps, vessels, piping subassemblies and/or Brown & .

Root supplied material that has been installed by a GiC or ,

a revision to the BRP used during that last walkdown shall identification / serial number or material 4

have their identification recorded on the System Verification Form I*

(Attachment 7).

All additional component supports shall be recorded on the BRP (reference paragraph 3.1).

3.3 N-5 WALXDOWN The , final status walkdown to verify completion of the piping

! system shall be performed using the "QC N-5 Checklist" (Attachment 3) and current BRP's , BRHL's , Vendor Certified or Design Reviewed Drawings.

The QCI shall record all component support numbers and _

general location on the respective BRP's.

3.4 RELEASE FOR PENETRATION SEALING The Area Management Penetrations Seals Supervisor shall notify QC Systems Superintendent of piping penetrations they want released for sealing.

The QC Systens Lead shall verify the penetration meets the.

following acceptance requirements:

a. All welds inside penetrations are completed , pressure tested and acceptable.
b. No base material defects.
c. Free of foreign ;naterial .

d. Hangers and permanent attachments required are ins talled.
e. Pipe clearance and gradient.

The QC Group will notify Area Management of penetrations acceptable for sealing. Prior to releasing a penetration for sealing, the Penetration Seal Release Form (Attachment 4) l shall be completed and submi tted to the ANI for his concurrence. Completed Penetration Seal Release Forms shall be forwarded to Area Management.

3.5 COMPONENT SUPPORT DESIGN VERIFICATION The QC Systens Leads shall be responsible for performing an inspection of all ASME component supports to verify they are in compliance with the vendor certified (Large Bore) or design reviewed (Small Bore) drawings.

I

! Inspections of component supports shall be performed using the "QC Component Support Checklist" (Attachment 5).

Any welds on component supports that are not required by the vendor certified or design reviewed drawing shall be inspected in accordance with the requirements of Reference .

1-B but actual weld sizes do not have to be documented. -

3.6 SYSTEM / SUBSYSTEM DOCUMENTATION All items defined on the "QC Checklist" as unsatisfactory shall be documented on the "QC Punchlist" (Attachment 6).

Base material defects and arc strikes shall be identified and resolved per Reference 1-C, in addition to being r3 corded on the "QC Punchlist".

When the prerelease walkdown is completed, the QC leads shall t eturn walkdown documentation supplied by Quality Ea jinee-ing and a copy of the "QC Punchlis t" to the QE Completions / Start-up Group for coordinating resolution of punchlist itens (Reference 1-D).

I The QE Completions / Start-up Group shall notify the 4

{ responsible QC Systens leads when the "QC Punchlist" items

' have been corrected by returning their copy of the Punchlist

! and supporting documentation to the QC leads. The corrected

! itens will be reinspected to verify acceptability and a copy

! of the punchlist returned to the QE Completions / Start-up Group.

Any unsatisfactory items that require an Engineering evaluation or rework will be identified on NCR's in accordance with Reference 1-C.

A system or portion of a system shall not be considered completed until Quality Assurance has verified through the above mentioned QC walkdown and QE Systems documentation review that all permanent piping, valves, pumps and hangers are complete and intact and have been installed in accordance wi th current design documentation (i.e., BRP drawings, BRHL's , BRH's , GHH's , CNC 's , etc. ) . Also the pressure test shall have been completed and accepted by the ANI and the Owner in accordance with Reference 1-E.
